One processed image (AS3, registax) taken out of several hours of rotation captured.
Based on that video (raw footage red channel), how would you rate that seeing ?
I think I was at critical focus; I tried later on to adjust but never managed to get that sharp (could also be seeing degrading over night). It's really not easy sometime to focus on planet, especially with a lot of backlash and mirror shifting with the celestron focus motor.
Equipment: ZWO 290mm mini, celestron edgehd 8", barlow omni2x (f20, so more like x6-7)
